Ralmike tooling needs identification.

maxroeder@gmail. · Aug 13, 2018

Because most all Ralmike information is lost to history I need to identify a set of Ralmike tooling fixtures. I purchased a very little used J Head, 1971 Bridgeport and these two items came with it. Never seen them before but I'm sure someone has. Please help with telling me what these are used for.

I have one of those, they are table squares for lack of the maker's designation or name. There are 2 oblong pins that fit closely into the holes and also fit into the mill table slots to align a part with the slot or 90° to the slot. I haven't measured the hole positions, there may be combinations that make common angles as well.

The holes are probably to re-align either X or Y.

Thanks guys, makes total sense now. Need to check if hardened face rail has an slight angle to force part holding down to table. may be a good tooling item when used with edge clamps.
